Keith, Attached a pic of the side of slide, the whole coach was cleaned with Aero Wash/Wax nothing else. For the price of a gallon and some microfiber clothes you can't go wrong.
I use a bucket full of clean water and two clothes, get one damp, spray on the Aero wipe with the damp cloth then with the dry one. When the damp/wet one gets dirty rinse it out with the clean water and repeat, and repeat and repeat, you get the idea. I used it one everything except the tires.
Give it a try, I also use it on the car and the Yamaha ATV.
